Slide, not really. If mono SIMD had a more general mapping to the GPU, or
could operate on very large vectors or matrices, possibly. Linear algebra
is an easy mapping to that stuff. However, I do more complicated stuff
around timeseries,

send the link.
Below are code snippets to calculate Ordinary Least Squares, a simpler example.
I found this to be 4x slower than C++ / Java:

Hi,
I'd like to add that you may gain something on MS JIT compiler using
for (int i = 0 ; i x.Length ; i++)
instead of
for (int i = 0 ; i len ; i++)
This may seem counter intuitive, however that's the scenario in which
JIT eliminates array bound checking for the x array (however not for the
Hi,
I have pulled the repositories:
- http://github.com/mono/llvm.git
- http://github.com/mono/
And am on the mono-2.10 branch of the mono git repo and the mono branch of the
llvm git repo. The build proceeded smoothly until attempting to build the
LLVM backend mapping in mono/mini:
Hi again,
It is too bad that one cannot declare a primitive expression to be
locally const in C#.
Maybe one could get away with something like this:
public struct FinalBoxT
{
public FinalBox(T value)
{
this.value = value;
}
public T
Yes, I see what you are doing. There is no way to modify the structure.
However doesn't it still boil down to determining whether a local variable
reference is changed. So for instance:
FinalBoxint len = some expression
for (int i = 0 ; i len ; i++)
do something on array[i]
vs
var

Yeah, exactly, this is rather pointless construct ;) There
On the other hand, maybe it could be possible to add the final-like
mechanism to Mono's compiler. Such mechanism would be beneficial if the
CLR had some notion of local readonly variables. F# uses non-mutable
variables a lot, so maybe CLR recognizes it. I am not sure what kind of

As far as I know the final on local variables is only a hint for the java
compiler (javac), not jit (hotspot) engine. Detection of loop invariants is
done at runtime (during code jitting) so there's really no difference
between any of the following in modern Java jits:
1) (final) int max =
Yes, the modern java JIT does not need final as does the analysis. However,
it is very nice to be able to specify constness, not only to help the JIT
along, but also in terms of documenting intent. Given that C# does not have
such a construct (too bad) / const is too constrained, the next
Hi,
You should use the 'mono-2-10' branch of the llvm repo.

Mono is a framework, which includes compiler and runtime.
It's a reimplementation of the .NET framework.
How you use it depends on your goals.

Mono is mostly used in two ways:
1- Embedding c# code and using c# as a script language. There are a few
games that did this and the number will increase in time since c# is
much more suitable for scripting than python or lua.
2- Running c# codes in non-windows platforms.

Hi all
I am curious the first scenario: embedding c# code and use it as a
scripting language. As regards the size of runtime, it usually bigger than
others like lua or even python, so what is the advantage?
